About

Professor Bebej's research focuses on the evolutionary history of aquatic mammals, including cetaceans (whales, dolphins, and porpoises) and pinnipeds (seals and sea lions). He is especially interested in the earliest stages of these land-to-sea transitions, in order to understand how the terrestrial and semiaquatic ancestors of these animals became increasingly adapted for aquatic life. His work has focused on the structural and functional changes of the vertebral column and the evolution of derived modes of aquatic locomotion.

When he isn’t working, Professor Bebej loves spending time with his wife, two sons, and dog. He is a huge St. Louis Cardinals and University of Michigan fan, and he enjoys baseball, basketball, running, reading, watching movies, photography, and playing German-style tabletop games.

Academic Interests

Professor Bebej's academic interests include comparative anatomy, functional morphology, vertebrate paleontology, and the evolutionary history of mammals. In the past, he has worked on fossil horses and pinnipeds, but most of his research has focused on fossil cetaceans. For his doctoral work at the University of Michigan, he studied an enigmatic group of fossil whales from the middle Eocene of Pakistan called remingtonocetids. His research focused on their postcranial skeleton and utilized multivariate statistical analyses and three-dimensional multibody dynamic models to test hypotheses of vertebral function. In 2009, he spent two months on a paleontological dig in Egypt, where he helped to excavate the skeletons of fossil whales at Wadi Al-Hitan, a UNESCO World Heritage Site in Egypt's western desert. He routinely spends time working in collections at world-renowned museums (including the National Museum of Natural History at the Smithsonian Institution in Washington, DC), where he studies the anatomies of modern mammals to aid in the interpretation of fossil forms. Professor Bebej is also interested in the relationship between science and Christian faith.

Research

Professor Bebej's current research focuses on the transition from foot-powered to tail-powered swimming in the earliest fossil cetaceans.
